According to the Red Wing Collectors Society, Your 25 gallon crock with 4 birch leaves would be worth $300.00 to $350.00! If it is in perfect condition!
20 gallon redwing crock
The value depends on condition and maker.
In good condition ...no cracks ....about 190.00
50-75 dollars
It depends on the era of the pot, who painted the crock, and is it collectible?
$300
A general rule of thumb is that crocks are worth about $10 per gallon wholesale. Rarity will of course increase the value.
I have one also. A live auction site said $100 to $300. But there is one on Ebay right now with no bids. Maybe shipping is more that the crock is worth. Not sure.
It all depends on condition. If its not chipped or cracked and the finish isn't worn you might get $100 for it.
Depending on the condition it could go for between $100 and $300. Other factors include the clarity of the signature stamp.
* * One way is to check antique shops and see what they are going for, or check on E-bay to see what this size crock brings.
Yellow or Black Birch is very good firewood, high heat value, slow burn. White or Gray Birch is average- better than some, not as good as some.
